MACHINE FOR STlFFENING HAT-CROWNS.

SPECIFICATION forming part of Letters Patent No. 519,195, dated May 1,1894. Application filed September 29,1893. Serial No. 486,780. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, FRANKJ. MURPHY, a citizen of the UnitedStates,residing at Danbury, inthe county of Fairfield and State of Connecticut,have invented certain new and useful Improvements in Machines forStiffening Hat-Crowns; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothhas for its object to simplify and improve the construction andoperation of the machine, the special purpose being by improvements inthe details of construction to increase the product of the machine, thework being done just as well as heretofore, but the construction beingsuch as to enable the operator to handle the hats more rapidly and toavoid loss of time between the finishing of the 0peration upon one hatand the commencement of the operation upon the next hat.

With these eudsin view I have devised the scale taken on the line x a:in Figs. 2 and 5 .illustrating the clutch mechanism and also themechanism for operating the expansible cone; Fig. 4 a section on theline y y in Fig. 3 looking down; Fig. 5 a section on the line a z inFigs. 3 and .4; Fig. 6 an elevation corresponding with Figs. 3 and 5 thepoint of view being opposed to that in Fig. 3and from the right in Fig.5; Fig. 7 an enlarged sectional view of one of the parts or arms of the1 expansible cone showing .the mechanism for.

' clamping the hat body on the cone, and Fig.

8 is a plan View corresponding with Fig. 7.

1 denotes the bed of the machine which is supported by suitable legs 2,and is provided 5 5 shown as provided with two belt pulleys so I as toprovide for different speeds for different classes of work. Motion isimparted to the carriage by means of a connecting rod 10 one end ofwhich is pivoted to the tcarriage the other being adj ustably connectedto gear wheel 5 so that theextent of movement of the carriage may beregulated at will.

11 and 12 denote respectively rear and front boxes in which shaft 8 isjournaled. The rear boxiis provided with an arm 13 which is pivoted to abracket 14 on a cross piece 15 between therear legs. Box 12 is providedwith an arm 16 having a slot 17 and at its upper end a book 18. Abolt 19passes through slot 17 and through a bracket attached to a cross piecebetween the legs the same as at the other end of the machine.

20 is aspring one end of which is connected to the under side of the bedthe other being connected to hook 18 upon box 12.

21 is a foot lever pivoted to a bracket 22, and 23 is a link connectingthe foot lever to box 12. i i 1 i The parts just described all appear inFig.

1 in dotted. lines and are fully described in or. the said Patent No.426,135. v

The operation is precisely as in the former patent. Spring 20 acts tohold the worm. in engagement with gear wheel 5 so that the carriageiscaused to reciprocate continuously 5 until its movement is stopped bythe operator pressing down upon the foot lever and disconnecting thewormfrom the gear wheel.

24 denotes a spindle which is mounted in boxes 25 on standards 26extending upward :00 from turning plate 27 which is secured to the-.carriage by a bolt 28.

29, see dotted lines Fig. 2, denotes anti-friction rollers upon whichplate 27 rests and turns freely.

The cone used in my present machine is practically identical with thecone which forms the subject of my said former patent,

the lower end of which ispivoted to the turn- This lever is provided ingplate as at 33. with an enlargement 34 having an opening through whichthe slide passes, the connection of the lever to the slide being bymeans of screws 35 and 36 which engage a ring 37 lying in an annularrecess in the slide. This I slide is secured to the spindle so as toturn which the shaft is journaled, and 43 a tank for the stiffeningmaterial. This tank is provided with a solid trunnion 44 and a hollowtrunnion 45, the former engaging a box 46 and the latter engaging a box47 which also receives a pipe 48 which is in line with the hollowtrunnion, and the other end of which passes into hollow shaft 40 whichturns freely thereon.

49 denotes a stop cock in pipe 48 for the purpose of cutting off theflow of stifiening material to the brush.

The tank is retained in upright position by, means of a set screw 50 inbox 46 which engages solid trunnion 44. Should it be desired at any timeto empty the tank of its contents, as for example for cleaning or forchanging the quality of the stiffening material, this set screw isloosened which permits the tank to be turned on its trunnions and thecontents Boxes 46 and 47 are carried by emptied out. standards 51 whichare themselves supported by an extension 52 from the bed of the machine.The operating lever is locked in any required position after the conehas been expanded within a hat body by means of a special form of catchwhich I have devised for this machine, it being essential that the conebe locked rigidly in the expanded position and at the same time that thelocking mechanism be so constructed that it will work smoothly andeasily, and all danger of slipping in use shall be avoided.

53 denotes a plate which is secured to one of the standards 25 and isprovided with a slot 54 and a rack 55.

56 and 57 denote upper and lower arms swung toward the sizing brush.

which are pivoted to the lever. The lower arm is provided with a lug ortooth 58 which engages the rack, the lug being held in engagement withthe rack by means of a spring 59 which lies in a socket 62 in theupperarm and bears against the lower arm.

I 60 denotes arms which extend downward from arm 56 passing onoppositesides of arm 57 and the rack and between which is pivoted aroller 61 which engages slot 54.

63 is a hand piece which is pivoted to operating lever 32. A link 64connects one arm of this lever with lower arm 57. In the presentinstance I have shown the link as passing through a slot in the upperarm.

The operation of the catch as a whole will be clearly understood fromFig. 3'in connection withFig. 1. The operator moves lever 32 forward asfar as may be necessary to expand the cone to the required size. As thelever is moved forward lug 50 will move over the ratchet and will lockthe lever against backward movement in any position in which it may beplaced. To contract or collapse the cone the operator lifts the lug fromthe rack by means of the hand piece which leaves the operating leverfree to be moved backward.

In order to insure that each hat body while upon the cone shall beoperated upon evenly by the stiffening brush so that the bodies will bestiffened uniformly without regard to their size and the consequentexpansion of the cone, I provide a stop 65, in the present instance aroller carried by plate 66 which is itself bolted to any suitableportion of the machine, said stop being adapted to' be engaged by an adjustable guide plate 67 each time the turning plate, spindle, cone, &c.,are This guide plate is pivoted to the forward end of the turning plateas at 68, see Fig. 4, and is provided at its rear end with an obliqueslot 69. This slot is engaged by the lower end of a stud 70 which hasformed integral with it a guide rod 71. The stud is provided with ananti-friction roller 72 which lies in the slot in the guide plate, thestud itself moving in a slot 73 in a plate 74 one end of which is boltedto the turning plate, the other end extending upward and over the end ofthe guide plate. Stud 70 is pivoted to enlargement 34 of the operatinglever by means of screw 36,, see Fig. 5, which passes through the studand through the enlargement of the operating lever, and the inner end ofwhich engages ring 37. Guide rod 71 moves in a suitable support or guide75 carried by a bracket 76 which is bolted to one of the standards 26.It will be seen that the guide plate is adjusted simultaneously with thecone so that each time the turning plate, cone, &c., are swung intooperative position the cone must necessarily assume the proper posit-ionrelative to the stiffening brush to insure that the entire length of thebody be operated upon.

The hat bodies are retained upon the cone by a special form of clampwhich I have de-- Any number of thesei clamps may be used, although Ifind in prac-j vised for this machine.

tice that two which I place directly opposite each other on the cone arequite sufficient.

77 denotes the clamping arm which is in shape an angle arm and ispivoted in ears 78 at the end of the piece or arm of the cone to whichit is attached, see Figs. 7 andS. A spring 79 recessed in the end of thepiece or arm of the cone acts against the inner side of the clamping armto hold it in operative position. In order that the clamp may be adaptedto all sizes of hat bodies I provide a dicated by 87.

operator lifts the long armof lever 83 which moves the short armcarrying roller 86 in clamping plate 80 which is adj ustably secured tothe clamping arm by means of a screw 81 which passes through a slot 82in the arm.

Theclamp is operated by meansof an angle lever 83which ispivoted betweenears 84: upon the back of the clamping ar1n. One arm of this leverpasses through a slot 85 in theclamping arm and is provided at its lowerend with a roller 86 which bears upon the piece or arm of thecoue. Theconstruction of the clamp will be clearly understood from Fig. 7. .Itwill be seen that in the normal position of the parts the angle lever isinactive and spring 79 acts to press theclam ping plate down upon thebrim of the hat which is in- To release the hat brim the ward and liftsthe clamping plate against the power of the spring. A stop 88 is provided to limit the movement of the short arm of the angle lever inlifting the clamping plate. The stop is placed in the exact posilionrequired to retain the clamping arm and clamping plate in the raisedposition that the short arm back past the center which will permit thespring to act to press the clamp ing platedown upon the hat brim.

Spindle 24 and the cone are driven by means of a belt 90, see Fig. 2,which 1 passes over a drum 89 which is itself loose upon the spindle.One end of the drum is provided with a tapering socket 91 adapted toreceive a sliding cone 92 which is held against rotation on the spindleby means of a spline 93, but is free to move longitudinally thereon. ofthe incline of the cone, see Fig. 3, is an annular groove in which liesa ring 94.

95 denotes a lever which is provided with an enlargement 96 having anopening to receive the cone. Screws 97 pass through the enlargement oflever 95 and engage the ring. Thislever is pivoted to a bracket 98extending from one of the standards26,and is con-V nected by means of alink 99 to an operating lever 100 which isitself pivoted tothe turningplate, see Fig. 4. A stop screw 101 isprovided in this lever whichengages a stump 102 to limit the movement of the operating Back lever sothat the cone cannot be-forced hard into the socket, it being simplynecessary that the cone should engage the socket with sufficientfriction to carry the spindle and cone. Said lever 100 is the mainoperating lever by which the operator swings the turning plate, spindle,cone, 850., into operative position and holds the hat body in contactwith the stiffening brush and by which he re- 7 turns the parts to theirnormal position after each hat body has been operated upon.

103 denotes a wheel journaled on a stud 104 l which extends outward fromthe side of the bed. A rope 105 passes partially around this wheel andhas at its lower end a weight 106.

On the inner side of this wheel is a hub 107 to which a chain or rope108 is connected, the other end of said chain being connected to a hook109 on the carriage. As shown in Figs. 1 and 2 it will be seen that thecarriage,

spindle, cone, &c., are moving forward, that is toward the right. It isobvious that as this movement of the carriage takes place the weightwill act to turn the wheelandconse quently to wind the chain upon hub107. When the parts are in the position shown, the operator by means oflever 100 moves the sliding cone into engagement with the socket in thedrum which necessarily imparts .rotation tothe spindle and the conecarrying the hat body, and by further movement of said lever, stop screw101 being in contact with the stump, swings the turning plate, spindleand cone to the position shown in dotted lines in Fig. 2. The hat bodyon the cone is then in position to be operated upon by the stiffeningbrush, the operator holding the cone and hat body in this position bymeans of said lever 100, while the cone moves forward in ICC contactwith the brush. As soon as the stififening operation is completed theoperator using only said lever 100, moves the turning plate, spindle andcone back to their normal position and also disengages the sliding conefrom its socket so that rotation of the spindle and cone ceasesinstantly. During the backward movement of the carriage, turning plate,

850., the operator removes the hat body that has been stiffened andplaces another hat body thereon, it being simply necessary to manipulatethe two clamps as already described to release one hat body and secureanother in position. By the time the backward movement of the carriageand parts carried thereby is finished the new hat body will be readytobe operated upon. It will be apparent from Fig. 1 that while thecarriage has been moving backward, that is toward the left, a portion ofrope 105 will have been wound uponwheel 103 and the weight will havebeen lifted. When the parts are in this positiomin order to avoid lossof time, and so that the stiffening operation upon a new hatmay becommenced instantly the operator presses down upon the foot lever 21 anddisengages worm7 from the gear wheel. This leaves the carriage free tobe drawn forward by the weight, which the instant the gear wheel isreleased winds the chain upon hub 107 and draws the carriage. forward sothat the hat body upon the cone may be swung into position to be actedupon by the stiffening brush. I thus make a great saving of time, as thecarriage, spindle, cone, 850., will move instantly from the extremeretracted position into the position in which they are shown in Figs. 1and 2. In practice a suitable support, for example abracket 110 as shownin the drawings, is provided for the weight to rest upon at the extremeof its downward movement, that is to say the rope is given just therequired length so that at the instant the weight comes in contact withthe support and the forward movement of the carriage is stopped, thecarriage, spindle and cone will have been placed in sucha position thatthe cone may be swung inward and will place the tip of the hat body inposition to be acted upon by the'stiffening brush as the carriage ismoved forward by the worm and gear wheel, it being of course understoodthat the operator removes his foot from foot lever 21 gear wheel, ofwheel 103 having a hub 107, a; chain connected to the carriage and tosaid hub, aweight, a rope connected to said weight and passing partiallyaround the wheel, and

a support for the weight whereby the forward movement of the carriage islimited said parts being so arranged that when the carriage is movedbackward the rope is wound on the wheel and the weight lifted, and whenthedriving mechanism is disconnected from the gear wheel the weight willact to draw the carriage forward independently of the gear.
